There's no real answer to a question like this, but a fairly simple pattern that the first four examples fit is to re-interpret the + symbol to mean "add two operands, then multiply the result by the first operand." That is, a + b, expressed with the ordinary meaning of the + sign, is a * (a + b). 

2 * (2 + 3) = 10, etc.

In the last example,

9 * (9 + 7) = 9 * 16 = 144.

In some computer languages, it is possible to redefine or "overload" symbols such as +. Thus, with a few lines of code, one could create an environment in which the expression 9 + 7 really would have the value 144.

I am truly grateful to all of you for your answers. :)

 

You are totally right. The right answer is 144.

 

Special thanks go to Dan Smith for giving us more details about the calculation. Thank you :)
